Unable to press forward with that technology, Moderna has had to focus instead on developing a handful of vaccines, turning to a less lucrative field that might not justify the company’s nearly $5 billion valuation.
“It’s all vaccines right now, and vaccines are a loss-leader,” said one former Moderna manager. “Moderna right now is a multibillion-dollar vaccines company, and I don’t see how that holds up.”
In need of a Hail Mary
Founded in 2012, Moderna reached unicorn status — a $1 billion valuation — in just two years, faster than Uber, Dropbox, and Lyft, according to CB Insights. The company’s premise: Using custom-built strands of messenger RNA, known as mRNA, it aims to turn the body’s cells into ad hoc drug factories, compelling them to produce the proteins needed to treat a wide variety of diseases.
But mRNA is a tricky technology. Several major pharmaceutical companies have tried and abandoned the idea, struggling to get mRNA into cells without triggering nasty side effects.
